在WEB-INF文件夹下新建web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <display-name></display-name>    
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <filter>
      <filter-name>struts2</filter-name>
      <filter-class>
          org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
      </filter-class>
  </filter>
  <filter-mapping>
      <filter-name>struts2</filter-name>
      <url-pattern>/*</url-pattern>
  </filter-mapping>
 </web-app>

在src\main\resources文件夹下新建struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
    <constant name="struts.devMode" value="true" />
    <package name="base" extends="struts-default">

        <action name="login" class="base.web.action.login.LoginAction"
            method="login">
            <result name="success">WEB-INF/success.jsp</result>
            <result name="error">WEB-INF/error.jsp</result>
        </action>
    </package>
</struts>

在src\main\java文件夹下新建LoginAction类

package base.web.action.login;

public class LoginAction {
    private String username;
    private String password;

    public String login() {
        if (username.equalsIgnoreCase("111")
                && password.equalsIgnoreCase("222")) {
            return "success";
        }
        return "error";
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

}

修改index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
   pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
   <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" 
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>登录</title>
</head>
<body>
   <h1>登 录</h1>
   <p>帐号： 111,  密码：222 </p>
   <form action="login">
    帐号： <input type="text" name="username"/><br/>  
    密码： <input type="password" name="password"/><br/>  
      <input type="submit" value="提交"/>
   </form>
</body>
</html>

在WEB-INF文件夹下添加success.jsp和error.jsp

success.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<html>
<head>
<title>登录</title>
</head>
<body>
    登录成功！！！
</body>
</html>

error.jsp:

<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<html>
<head>
<title>登录</title>
